What is water pollution?

Water pollution is defined as the presence in groundwater of toxic chemicals and biological agents that exceed what is naturally found in the water and may pose a threat to human health and/or the environment. Additionally, water pollution may consist of chemicals introduced into the water bodies as a result of various human activities. Any amount of those chemicals pollutes the water, regardless of the harm they may pose to human health and the environment.

Causes:

Chlorinated solvents commonly used in industry are examples of such chemicals polluting our water exclusively due to human activities.Regardless of their provenance, the chemicals or biological agents causing water pollution are generically referred to as water pollutants.The chemicals or biological agents causing water pollution are generically referred to as water pollutants. 

Types of water pollutants

I) Chemical – when various chemicals are the water pollution causes.

II) Radiological – when radioactive materials are the water pollutants causes.

III) Biological – when various microorganisms (e.g., bacterial species and viruses), worms, and/or algae occurring in a large number are the water pollution causes. This type of pollution is caused by decaying organic material in water, animal wastes, as well as improper disposal of human wastes.
